Citroen DS 23 Pallas
The Citroen DS 23 Pallas represents the pinnacle of one of the most revolutionary automobiles ever created. The DS, first revealed at the 1955 Paris Motor Show to stunned silence followed by thunderous applause, spent its entire 20-year production life as the most technologically advanced mass-produced car in the world. The 23 Pallas designation combined the largest engine displacement offered in the DS range with the most luxurious trim level, creating the ultimate expression of Citroen's singular automotive vision.
The DS 23 was powered by the 2,347 cc version of Citroen's inline four-cylinder engine, producing approximately 130 horsepower with electronic fuel injection. While this output may seem modest, the DS was never designed to compete on power figures. Instead, its supremacy lay in the extraordinary sophistication of its chassis and body engineering. The revolutionary hydropneumatic suspension system, which used nitrogen-filled spheres and hydraulic fluid to provide self-leveling capability and adjustable ride height, delivered a quality of ride that no other production car could match.
The Pallas trim level, introduced in 1964, added significant luxury appointments to the already well-equipped DS. Leather upholstery, additional chrome trim, improved sound insulation, and enhanced interior fittings distinguished the Pallas from standard DS models. The combination of the Pallas specification with the 23's larger engine created a vehicle that was simultaneously the most comfortable and the best-performing DS variant, the ideal choice for the discerning owner who demanded the complete DS experience.
The DS's hydraulic system extended far beyond the suspension. The brakes, steering, clutch, and even the gear selection mechanism all operated through a central hydraulic circuit powered by an engine-driven pump. This integration created a driving experience unlike anything else on the road, with fingertip-light steering, effortless braking, and a semi-automatic transmission that eliminated the clutch pedal entirely. The system required a period of acclimatization for new drivers but rewarded familiarity with an extraordinarily refined experience.
Flaminio Bertoni's exterior design, which had caused a sensation in 1955, remained remarkable throughout the model's life. The aerodynamic body with its covered rear wheels, flush headlamps (later becoming the famous swiveling directional headlamps), and dramatically low hood line created a silhouette that appeared to come from decades in the future. The DS looked as modern in the 1970s as it had in 1955, a testament to the purity of Bertoni's vision.
The DS 23 Pallas was produced during the final years of DS production, from 1972 to 1975, and represents the most refined iteration of the design. Today, it is highly prized by collectors who appreciate the DS's unique combination of engineering innovation, design excellence, and ride quality. The hydropneumatic suspension system, while requiring knowledgeable maintenance, continues to function remarkably well when properly serviced, allowing modern drivers to experience the extraordinary comfort that made the DS legendary.
The hydraulic system is the critical area for inspection. Check all hydraulic spheres for proper pressure (they require periodic recharging or replacement). The main hydraulic pump and accumulator must function correctly for brakes, steering, and suspension to work. Rust can affect the body structure, particularly sills and floor pans. Injection-equipped DS 23 engines require specialist knowledge. Ensure all hydraulic functions work before purchase.
The DS 23 was produced from 1972-1975 as the final evolution of the DS range. Total DS production across all variants exceeded 1.45 million units from 1955-1975. Pallas trim was available across multiple engine specifications.
